SPECIFICATION forming part of Letters Patent No. 607,165, dated July 12, 1898. Application filed August 22, 1894 Serial ITO- 521,045. (No model.)

To all whom, it may concern:

Be it known that LFRANCIS J OSEPH FREESE, of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have: invented certain new and useful Improvements in Sole-Cutting Machines; and I do cutting of the blank and the freeing of it from the die or cutter without using any additional means for so doing; secondly, the adjustment of the die or cutter to produce various sizes and shapes of blanks; thirdly, the use of a movable stoclnsupporting table which presents a different part of its surface to each impact of the die, thus maintaining an even surface, and allows of a ready adjustment of the stock into position to be cut by the :die

and of retaining it in such position, thetable furthermore being adjustable in working distance relatively to the die for various purposes, and, lastly, the possibility of stopping the machine at any desired point in its operation.

The invention consists in the several devices, arrangements, and combinations of parts hereinafter described,and particularly pointed out in the claims, and for full comprehension thereof reference must be had to the annexed drawings,forming a part of this specification, in which like symbols indicate corresponding parts, and wherein Figure 1 is a front elevation of the complete machine; Fig. 2, a side elevation of same; Fig. 3, a side elevation of same similar to Fig. 2, but partly broken away; Fig. at, a horizontal section of machine on line 11:, Fig. 1, looking in the direction indicated by arrows. Fig. is a horizontal section on line g y,Fi'g. 1,-Figs. 6 and 8 being enlarged detail front views of the mechanism for operating the cutter. Fig. 7 is an enlarged detail view of the upper front portion of the machine with face-plate re- Fig. 9 is an enlarged vertical section of the upper front portion of the machine, taken on line as, Fig. 7. Fig. 10 is a similar view to Fig. 9 of the same parts, but which are in different positions. Fig. 11 is a horizontal section of the die or cutter on line -Z- Z, Fig. 7, and looking in the direction in 'dicated, Fig. 12 being a detail view of the clutch-shipper and Fig. 13 being a detail perspective view of auxiliary widening-plate.

'Heretofore in the class of work known as sole-cutting it has been the practice to use hand-operated parts and devices with consequent loss of time and considerable expense, and to avoid such objections I provide a power-driven machine having a main driving-shaft carrying eccentrics acting directly upon the carrying parts for the cutter or die, with a consequent direct and more powerful and positive operation of such die, and in order to avoid any necessity for the use of special means for freeing the blanks from the die after being cut I make such die in two parts, each operated independently and alternately, so that when one part has finished cutting a portion of the blank and is Withdrawing the other comes into engagement with the work and in' the act of cutting the remaining portion of the blank disengages it from the pre- Viously-operating part.

1 1 are suitable legs supporting a table 2, having a centrally-located web 3 extending vertically therefrom and having recesses or portions cut away at -l, 5, and G to accommodate, respectively, the supporting-table, the eccentrics for operating the cutter, and the clutch-shipper, and such web also having enlargements 7 and S, which are cored and in which are respectively located the parts carrying the supporting-table and the main 0perating-shaft wit-h its clutch, a third enlargement 9 having a vertical recess, which is covered by a removable face-plate 10.

11 is the main driving-shaft, which carries a drivingpulley 2, clutch mechanism 'to be hereinafter described, and eccentrics 13 and 14.

15 and 16 are vertically-operating slides or parts carrying the cutters l7 and 18 and located in the vertical recess in the enlargement 9. These slides are slotted, as at 19, about midway of their length, and in the slots are located springs 20, which bear downward at one end upon a fixed bar 21 (passing through the face-plate 10 and the slots'into the web behind the slides) and at the other .and cast in one therewith.

end upward against the top end of the slots in order to normally elevate such slides into contact with the eccentrics 13 and 14, the lower ends of the slides being diminished in thickness and bent at right angles to form flanges 22, to which the cutters can be secured in any desired way, but preferably by bolts passing through back plates, to which the cutting parts proper of the cutter are secured.

The cutter or die proper, as illustrated more particularly in Fig. 11, is divided into two parts preferably by a dividing cut extending, longitudinally and centrally of the cutter, and each part comprises an innerbody or frame piece a, which is formed integral with a back plate I), and has its outer side or edge shaped to conform to that of the removable cutting blade or strip 0, attached to it, as shown in detail in Fig. 1], by screws 0', having shoulders c 0 formed in one therewith and between which the strip 0 is located, so that upon the screws being turned in or out the cutting form or contour can be varied to a considerable extent.

In order to facilitate the shaping of the edge of the framepieceflt is originally formed with a series of notches or recesses d, thus diminishing the amount of metal to be operated upon in shaping.

To enlarge or laterally expand the size of the cutter as a whole, an auxiliary or enlarging cutting plate or section comprising a frame-piece c and cutting-blades f f at each end is inserted between the two parts of the cutter and secured to either of them, but preferably to the one 18 by screws 9. The part 17 of the cutter is secured to the flange of carrier-slide by bolts h, passing through slots j in the flange and enteringits back plate, and after being adjusted sidewise into its proper central position remains in such position, while the part 18 is similarly secured to the flange 22 of the carrier-slide 16; but the slots is in the flange in this case are wider to allow of adjustment in any direction, as will be required in setting it in proper position relatively to the other part 17, and also when the cutter or die as a whole is being widened by the insertion of the auxiliary plate cf. (Shown in detail in Fig. 13.)

The work support or table may be the enlargement of the web suitably faced for different kinds of work; but I prefer to use a separate tableof a special form and carried by such enlargement. This table is constructed so as to be rotated and have a vertical adjustment as follows:

.23 is a base, preferably of metal, and having upward projections 24, perforated, as at 25, Upon the base rest two rings or annuli 26 27, each having one edge out to form an inclined plane, the inclined plane of one corresponding with the inclined plane of the other, so that when they are set one on top of the other, with their inclined faces in contact, as shown in Figs. 9

and 10, the top edge of the uppermost ring 27 will be parallel with base The upper inclined edge of the lower ring 27 has a notch or recess 27 to receive a square screw-bolt 27, having a round screw-threaded end to receive a nut 27, a portion of which and a portion of the head of the bolt overlapping the lower inclined edge of the upper ring 27, and when such nut is tightened will clip the upperand lower rings and retain them. Upon the uppermost of these rings is placed a circular block of wood or other like material, which is secured in place by screws passing through the perforations in projections 2t, which projections extend upward a sufficient distance to allow of such connection.

From the under side of and having a screwthreaded connection with base 23 a vertical shaft 28 projects downward through the perforation 29 in enlargement 7 to accommodate it, through the forward forked end 30 of a bracket 31, secured to the under side of tablesection 2, and also through a gear-wheel 32, carried by such bracket and with which gearwheel it (the vertical shaft 28) has a featherand-spline connection. Bracket 31 has a lateral extension 33, perforated to form a bearing for a horizontal shaft 3%, carrying on its forward end a worm 35 to mesh with gearwheel 32. The other or rear end of this shaft is carried in bracket 36 and carries near its end a ratchet-wheel 37, which latter and the shaft 28 are operated by means to be presently described. The table is yieldingly normally elevated into contact with the cutter by means of springs 36 located in sockets 37 in the upper face of the enlargement 7 of the web, and having their upper ends bearing beneath the under side of the base of the table, and in order to lower the table to allow of the stock being placed between it and the cutter a treadle 3S, fulcru med at 39, is connected by means of a chain 40 and swiveling joint L1 to the lower end of shaft 28, such swiveling joint being necessary, so as not to interfere with the rotation of the table.

In order that the machine can be stopped at any desired point in its operation, I prefer to use the form of clutch and operatingmeclr anism therefor now to be described. The clutch proper consists of a sleeve 42, having a featherand -spline connection with the driving-shaft 11, so as to be capable of sliding thereon and rotating same when moved into clutch with the clutch-face of driving wheel 12, which movement is effected by means of a spring 43, located in a recess -14, formed in the enlargement S and encircling the shaft 11, the spring bearing at one end against the inner end of the sleeve -12, entering an enlargement of the outer end of the recess4-1-,while the other end of the spring bears against the inner end of the recess. The

clutch-sleeve 42 is normally held out of engagement with the d riving-pulley by means of a projection 45 on its periphery, which en gages the upper end of the vertical arm of a bell-crank lever 46, fulcrumed at 47 to the web 3. This vertical arm is normally kept in a position to allow of the engagement of projection 45 therewith by means of a spring 51, bearing upward upon the under side of treadle 49, fulcrumed at 50, and the rod 48, having its lower and upper ends connected, respectively, to the treadle and horizontal arm of the bell-crank lever. By the depression of the treadle the vertical arm of bell-crank lever 46 is thrown laterally out of the way of the projection 45, thus allowing the clutchsleeve 42'to be thrown forward by the spring 43 into clutch with the driving-pulley and the driving-shaft thereby rotated.

As a single rotation of the driving-shaft is sufficient to enable the cutter to complete its work and as it is desirable to stop the machine immediately after, I arrange for the automatic disengaging of the clutch-sleeve from the driving-pulley by forming the upper end of the vertical arm of the bell-crank lever 46 with an inclined face, with which the projection 45 (preferably also formed with a correspondingly-inclined face) on the sleeve 42 engages as the single rotation of the driving-shaft finishes, so that the sleeve is forced out of clutch with the driving-pulley and the driving-shaft consequently stopped. In order that an absolute determining of the time at which the driving-shaft will cease its rotation or a perfect adjustment of parts to that end can be secured, I prefer to make the end of the vertical arm of the bell-crank lever in a separate piece and adjustably connect same with the arm proper by slot 52 and setscrews 53.

As previously mentioned, the work-supporting table is connected with the shaft 34, carrying the ratchet-wheel 37, and in order that it may be intermittently rotated through such and the other parts described a pawl 54 is carried by the rod 48 to engage the ratchet upon each depression of the rod, with the result that the tableis rotated for an extremely short distance, allowing the table to continually present a different part of its surface to each impact of the cutter, thus maintaining an even surface.

The normal position of the operating parts of my machine is as shown in Fig. 1.

In the operation of my machine the table 23 is first drawn away from the cutter or die by depressing treadle 38 to allow the stock to be set in place, as shown in Fig. 2, after which on the treadle being released the table will, through the action of springs36, press the work up against the cutter. (See Fig. 10.) Treadle 49 is then depressed, which, through rod 48, causes vertical arm of bell-crank le ver46 to release projection 45 of clutch-sleeve 42 and allow spring 43 to force the latter into engagement with driving-pulley 12, thereby causing the rotation of main shaft 11 and with it eccentrics 13 and 14. By the downward travel of rod 48, caused by the depression of treadle 49, pawl 54, carried by such rod, en-

gages ratchet-wheel 37 and through it, horizontal shaft 34, worm 35, gear-wheel 32, and vertical shaft 28 rotates the work-table a small degree and presents a smooth surface for the dies to cut upon. As will be seen by reference to Figs. 6 and 7, eccentric 13 will commence action first and through slide 15 will cause the part 17 of the die to cut onehalf of the required blank, as shown in Fig. 9, and as it completes its downward and commences its upward stroke the eccentric 14 will have caused, through slide 16, the part 18 of the die to reach and commence cutting the stock and at the same time hold the stock against displacement by part 17 as it is raised through its carrier by spring 20. The part 18 of the die,finishing its downward stroke, completes the blank and commences its upward stroke; but as it only has contact with half of the perimeter of the blank the friction will not be sufficient to cause part 18 to raise it from the table. Just before the main shaft during its rotation carries the eccentrics 13 14 around to the position shown in Fig. 6 to allow the springs 20 to raise the dies (through their carriers 15 16) to their highest point the projection 45 of clutch-sleeve 42 comes into contact with the inclined upper endof the vertical arm of bell-crank lever 46, and as it continues in its rotation for a small degree further such projection 45 is caused to travel down incline 51, force the clutch-sleeve 42,0ut of engagement with driving-pulley 12, and stop the machine just as the dies reach their highest point.

To insure the severance of any undesirable waste from the remaining stock after the operation of cutting a blank and to leave the stock with a comparatively even edge, I secure to the portion 18 of the cutter or die, as will be seen by reference to Figs. 7 and 11, two auxiliary blades or cutters 71 7 2, extending a suflicient distance laterally from the die (see Fig. 7) to sever the waste upon the depression of the portion 18 of the die.
